With token generators + a good spread of mana costs, you put almost every creature in your deck into play in a single turn. With Eldrazi titans (or other graveyard shufflers) it's even easier, plus you can loop CITP/leaves play effects on any creature you have that way.

Token generators seem largely irrelevant, unless you have a lot of 1-drops you want to fetch.

Simic continues to be a treasure trove of type lines and now names, and on an amazing card too: Galloping Lizrog.

Also we have our first guildmage, Syndicate Guildmage, and it's a ... black ... burn card?? It's like that player loses 2 life but it can also hit planeswalkers. Interesting, I wonder if that will become more common in black.

The problem with the WWBB Wrath is that Fumigate exists and is better. Sure it costs 1 more, but is still easier to cast overall, can be played in way more decks, and will likely gain you 2x or 3x more life, on average.

Also, I'd run Wrath/Day/Damnation/Austere/Merciless Eviction all before I'd even consider this, outside some highly niche cases. But, I mean, it looks cool and gets the job done so if you just need a budget sweeper and you're in Orzhov I wouldn't scoff at you for running this.
